Abstract
Objective: To establish a HPLC method for determination of toosendanin in Yiganning Granules. Method: The determination was performed on a Agilent zorbax SB-C18 column (4.6 mm×150 mm
5 μm).Acetonitrile - water (30 ∶70) was used as the mobile phase.The flow rate was 1.0 mL·min-1 and the detective wavelength was set at 210 nm.The column temperature was at 35 ℃. Result: The linear range of toosendanin was 0.5-5.0 μg ( r = 0.999 9) and the average recovery was 97.11% (RSD 1.91%
n =6). Conclusion: The method is accurate
reliable and reproducible.It may well be used for the quality control of this product.
